Re: Raduino Replacemnt, COMING SOON!
You might consider adding pads for an AD8307, driving a Nano analog pin.
Very cheap on ebay.? Then this is a sweeperino, and a calibrated S-meter.

My Bitx is still open face on a piece of plywood, works fine..
Many are using unshielded plastic boxes as enclosures.
But if you are receiving interfering signals, a shielded?enclosure can help,
If you think you might need shielding, here's a few things to consider:
Interfering signals can come from gear like a faulty wall wart power supply, or a digital clock on the stove.
The microphone and speaker and power cables may need filtering to avoid RFI entering.
You might also want a common mode choke in the coax out to the antenna to prevent
signals (perhaps RFI) from getting picked up by the coax instead of only from the somewhat remote antenna.
Such shielding can also prevent the Bitx's? BFO, VFO, etc from interfering with other gear in the area.
Try the Bitx out in an RF quiet location with a portable antenna, see if that does away with any interfering signals.
?
A quick and dirty wrap around the outside of the rig with aluminum foil will determine if shielding helps.
I'd include a battery and speaker inside that wrap job, try it first without any antenna connected,
some interfering signals (birdies) will still be present due to harmonics of the local oscillators mixing.
Then connect an antenna into the wrap job, making sure the foil connects well with the shell
of the antenna coax connector

So a 4S battery pack would need to stop being used at 13.2V. With a
regulators' drop around 1.5V (we only pull 0.4-0.5A from the main
board on Tx, and the finals go strait to the battery), the final
voltage to the main board is around 11.7V. Quite a decent supply
voltage.
